If you created a free account at 000webhost, you may get Hostinger pop up Ads when accessing your website. Luckily I searched and figured out how to remove Hostiger Ads on 000webhost. Here is how you do it.

Step 1: go to this website: members.000webhost.com/analytics.php

Step 2: type your domain name and password -> Disable Code -> Submit

Congratulation! There will be no pop up ads on your website.

Or just move to Hostgator as Hosting Service with real customer support :)
